Using battery power
When a charged battery is in the computer and the computer is not plugged into external power, the
computer runs on battery power. When the computer is plugged into external AC power, the computer
runs on AC power.
If the computer contains a charged battery and is running on external AC power supplied through the
AC adapter, the computer switches to battery power if the AC adapter is disconnected from the
computer.
NOTE: The display brightness is decreased to save battery life when you disconnect AC power. To
increase display brightness, use the fn+f8 hotkey or reconnect the AC adapter.
You can keep a battery in the computer or in storage, depending on how you work. Keeping the battery
in the computer whenever the computer is plugged into AC power charges the battery and also protects
your work in case of a power outage. However, a battery in the computer slowly discharges when the
computer is off and unplugged from external power.
WARNING! To reduce potential safety issues, use only the battery provided with the computer, a
replacement battery provided by HP, or a compatible battery purchased from HP.
Computer battery life varies, depending on power management settings, programs running on the
computer, display brightness, external devices connected to the computer, and other factors.
Finding battery information in Help and Support
Help and Support provides the following tools and information about the battery:
●
Battery Check tool to test battery performance

Using Battery Check
Help and Support provides information on the status of the battery installed in the computer.
To run Battery Check:
1. Connect the AC adapter to the computer.
NOTE: The computer must be connected to external power for Battery Check to function properly.
2. Select Start > Help and Support > Troubleshoot > Power, Thermal and Mechanical.
3. Click the Power tab, and then click Battery Check.
Battery Check examines the battery and its cells to see if they are functioning properly, and then reports
the results of the examination.
